fla /104% W ?atenteel June 2% 11933 PATENT OFFIC MACHINE FOR MOISTENINGAND COOLING YARNS AND FABRICS Application filed September 19, 1931,Serial No. 563,800, and in Germany October 28, 1930.

This invention relates to a machine for moistening and cooling yarns andfabrics by means of three superposed rotatable rolls, the lowermost ofwhich is partly submerged 5 in liquid, supplies this liquid to themiddle roll running above it, whereas the uppermost roll serves as apressure roll for pressing the liquid into the material conductedbetween the uppermost roll and the middle roll.

It is known to construct in such machines one or more of the rollselastic and as lever loaded pressing roll, and to provide the lowermostapplying roll with engraving. All

these measures however serve merely to facilitate the application of thetreating medium, whereas in the known construction they were neitherprovided nor suitable for enabling a fine adjustment of the application29 according to the actual kind of material and to the actualrequirements, in the sense that the quantity of the liquid feed to theweb conducted through the upper roll gap is adjustable, both'as regardsthe quantities of treating medium supplied and also as regards thequantities of the treating medium squeezed out, namely independently theone ofthe other.

This object is attained for the first time 3;) by the present inventionin that an elastic applying roll is arranged under a middle engravedroll and a similar elastic roll above the same, two of the three r llsbeing adjustably loaded for pressing the liquid into or squeezing it outof the middle roll.

The arrangement may be such that one of the three rolls is stationary sothat the two remaining rolls act as pressing on rolls.

A particularly advantageous form of con- 'struction is illustrated byway of example in the accompanying drawing, in which construction theengraved middle roll is sta tionary, whereas the upper and lower rollsprovided with extensible, preferably rubber laggings are adapted to beadjustably pressed against the middle roll by lever loading, thepressing on pressure of the two rolls occurring independently the one ofthe other.

In the accompanying drawing: Fig. 1 shows the machine in side elevation.

Figs. 2a and 2?) show two forms of engraving of the middle roll.

Fig. 3 is a vertical section through the middle roll.

A middle roll 6, which in the example illustrated is stationary, isprovided according to the invention with engraving, and a roll a underthe roll 6 dips into a vessel 6, a squeezing roll 0 being arranged abovethe roll I). The rolls a and c are elastic in that they are made ofrubber or have an elastic or rubber lagging, and they are pressedindependently against the engraved middle roll Z) by levers providedwith adjustable weights 7 and f respectively. The middle roll I) may beengraved, as illustrated in Figs. 2a and 26, or in any other suitablemanner.

The operation of the machine is as follows particularly The submergedroll a transfers more or less 7 dressing liquid to the engraved middleroll 6 being adjustable, as desired, by its lighter or heavier pressure.The dressing liquid is supplied absolutely uniformly to the material (1passing through the machine by this enr, graved middle roll I), and thematerial is conducted between the engraved middle roll I) and the upperpressure roll 0 for the purpose of taking up the dressing liquid, sothat it absorbs the liquid on the engraved middle C roll 6, owing to thepressure of the upper roll 0. Owing to the different pressure exerted bythe lower submerged roll and the upper pressure roll against the middleroll more or less dressing liquid is taken up by the material passingthrough, it being possible to further finely regulate the quantity ofliquid according to the kind of fabric to be treated by making theengraving on the middle roll I) coarser or finer.

I claim:

A machine for moistening and cooling yarns and fabrics, comprising amiddle engraved roll, pressure rolls with resilient lagging arranged oneabove and the other below said middle roll, and adjustably weightedlevers adapted to independently press said pressure rolls against saidmiddle roll to accurately regulate the quantity of moisture supplied bysaid lower pressure roll to said middle and consequently by said middleroll to the material passing through the gap between said middle rolland said upper ressure cylinder and also the quantity of iquid squeezedout of the material by the pressure exerted on the material by saidupper roll on said middle roll. I

In testimony whereof I afix my signature.
